To ttZZ w/wm it may concern.-

Be it known that I, MIKAEL PEDnRsEN, a subject of the King of Great Britain, and a i resident of Raglan House, Dursley, in the f county of Gloucester, England, engineer, have invented a new and useful Gearing for Motor-Vehicles, Motors, Intermediate Motions, and other Mechanical Purposes, of

Which the following is a s ecification.

This invention has re erence to that form of gearing in which the whole mechanism revolves upon a stationary spindle to which spur-wheels can be locked so as to gear into spur wheels locked to loosely mounted planet spindles from which the motion is transmitted through the medium of a pinion to a main spur wheel, the object of the present improvementsbeing to so arrange such gearing as to enable the operator to change speeds by looking any of the spur wheels to the metal stationary spindle by friction clutches in a particular and y improved manner, and also b locking one of the spur Wheels to the shell or frame so as to have a direct drive and also, as for instance in motor cars to transmit the power from such gearing to the wheels through a balance or difierential gear as hereinafter described. Such an arrangement may be applied to motor vehicles, motors, intermediate motions and other mechanical purposes.

In order that this invention may be clearly understood and more easily carried into pracof drawingsupon which I have illustrated the natureof my said improvements.

Fig. 16 is a sectional planiof Fig. 14.

Like reference numerals refer to like parts throughout the specification and drawings.

In carrying this invention into efiect and referring to Fig. 1 of the drawings'the gearing mechanism is mounted upon the stationary spindle l and consists essentially of a series of spur wheels certain of which are one ,or more planet spindles 2 and arejpr'ovided to engage with spur wheels on the stationary spindle 1. The different speeds are obtained by locking certain of the spur wheels to the stationary spindle 1, in such a manner that they engage with other spur wheels fixed on the planet spindle or spindles 2 which revolve on bearings3. The power is then transmitted from the planet spindle 2 to the main spur wheel 4 which is mounted independently upon bearings 4 on the stationary spindle 1 and also as for instance in motor cars from thence through the medium of the balance or differential gear to the car wheel axles. I

- The different wheels are locked to the cen tral stationary spindle 1 by the longitudinal movement of rods 5, 6, which are actuated by the revolving or slidng cams 7, 8 and operate the friction clutches 13, 14 which will slide but not revolve on the stationary spindle 1 The cams 7, 8 are in the form of slots 9, and in order that the lateral movements of the rods 7, 8 may be regulated they are fitted with adjustable'blocks 9 seeFig. 14 against projections 11, 12 of the rods 5. 6. hear. I These blocks form the part of the cams where the actual locking takes place.

In the modification shown in Fig. '16 lever actuated'sliding cams 9", 10 are used instead ofthe aforementioned revolving cams, these actuate the rods 5, 6, through the medium of levers 9*, 10, when a longitudinal movement is imparted to them.

Referring back to Fig. 1, the rods 5, 6, of which one, two or more may be used are formed. flat at 15, 16 where they carry the projections 11, 12 for the cam slots 9, 10, so that a double cam 7, 8, may in sliding over these flat portions 15, 16 or projections carried by I same principle being brought into play when sliding cams are used. 1 When the rods 5, 6, pass through the hollow spindle 1 Fig. 1 they are connected to the sliding clutches or'spur wheels 13, 14 through the slot 17 in the spindle 1, each clutch or wheel 13, 14 having an inward projection 18 19 engaging preferably in one or more cross slots .20, 21 in the rod, provision being made for the rojection 22 on the rod to pass, the locking being effected by twisting the rods so that the projections 18,

19 on the clutch or wheel 13, '14 engage with the cross slots 20, 21 in the rods 5. 6.

Two rods 5, 6, may be efiectively provided to pass throughthe hollow 23 of the stationary spindle 1 in such'a manner that they slide on one another. One rod 5 can give three different speeds by operating a sliding clutch which will lock one loosely mounted spur wheel 24 against a shoulder or friction face '25 when moved one way. This clutch forms shoulders at 26 and 27 for another loosely mountedspur wheel 28 which carries a drum or cylinder 29 see Figs. 6 and 7 on which a 30 of which a part 30 is cut away and can slide laterally, but is prevented from turning by a projection 31 in the ring 30 engagin in a groove 32 of the-drum 29. This ring lies inwardly a seat .33 for the outer end 34 of a longitudinally adjustable toggle 35 the inner end 36 of said toggle 35 being seated in the drum 29. The shell'or frame 37 which is mounted on the stationary shaft 1 on the bearings 37 Fig. 1 has an annular seat or-groove 38 for the ring 30 allowing it to turn freel when not expanded. The toggle 35 wil however when at right angles to the spindle l expand the ring 30, thus creating a friction which will lock the drum 29 and consequently the spur Wheel 28 to the shell 37 and thereby give a direct drive.

In order that the ring 30 shall not engage with the shell due to centrifugal force or the.

like when the drum 29 is in either of the two end positions, it may be provided with jaws 30 30 which slide in slots 30 30 and hold it against the drum 29 when the latter is'in the two end positions but which slots or grooves 3030 are curved to allow of the expansion of the ring 30 when the sleeve 29 is in the middle position, see Figs. 6 and 7.

The drum or wheel 29 also has a friction face 39 so that by being pressed against another shoulder or friction face 40 on the stationary spindle 1 it is locked to the spindle 1 29 is bearing on the spindle at 29, 29", or

29, 29 when in the two extreme positions but bears on the shell at 37 b and 37 when. in

friction face 25 of the shaft.

the shell.

the middle position. For this purpose the seating on the spindle is reduced at l and 1 so as to leave an annular bearing face 1 which bears upon the raised bearing parts 29 and 29 of the spur wheels and drum 'seatings 28 and 29 in turn hear when in the two extreme positions, but are opposite the annular recesses Qt, 1, in the spindle 1 when in the middle posi ion. Projections 37 b and 37 inward in the shell 37 bear on the seating 29 and 28 of the combined drum and wheel when in the middle position. A sliding friction clutch operated by the second rod 6 Fig. 1 will lock another s ur wheel 42 against a shoulder or friction ace 43 which is facing the opposite way to the last named shoulder or face 40 and may be made in one piece 44. This shoulder 44 is screwed into its position. on the spindle 1 as shown in Fig. 13 to enable it to take the and thrust. To prevent it from twisting a key 45 fits into a recess 44 in the 7 The action of upward gearing roviding for four s eeds and a reverse isas ollows: For the hlghest speed the five spur wheels 24,

51, 52, 47 and 4 shown in Fig. 3 .are brought into use. The s ur wheel 24 is fixed upon the stationary s aft 1 by the rod 5 which.

looks it by means of the clutch 13 against the Thus when the shell 37 is revolved about the stationary shaft 1 motion is transmitted by the spur wheel 24 to the planet shaft 2 through the medium of spur wheels 51, mounted on stud 2, and 52. The motion is then transmitted from the planet spindle 2 by means of the pinion 47 to the main spur wheel 4.

For the second hig est speed the parts shownin Fig. 8 are brought into use. The

spur wheel 28 is locked to the shell 37 by means of the toggle actuated ring 30, the locking being operated by means of the rod 5 and clutch 13. This causes the spur wheel to revolve with the shell and consequently locks the planet spindle 2 by the spur wheel 53 which is in engagement with the spur wheel 28. The pinion 47 will also be locked, it being fixed to the planet spindle 2, and being in engagement with the main spur wheel 4 will cause the latter to revolve with Hence in thesecond highest gear the main spur wheel 4 is locked tothe shell 37 through the engagement of ring 30, toggle 35, spur wheel 28, spur wheel 53, planet spindle 2, and pinion 47.

For the third speed the parts shown in Fig. 9 are 1n use. The spur w eel 28 is locked to rod and clutch 13 which hold it against the gages with spur wheel shaft friction face 40. I On .the shell 37 being revolved the spur wheel 28 engages with the spur wheel53 on the planet spindle 2 and this motion is transmitted through the planet spindle 2 and pinion 47 to the main spur Wheel 4.

For the lowest speed the parts shown in Fig. 10 are in engagement.

The spur wheel 42 is locked to the station- 'ary spindle 1 by the action of the rod 6' and clutch 14 which hold it against the shaft friction face 43., On. the revolution of. the shell the planet s indle 2 transmits the motion by means 0 spur wheel 54 which en- 42 and pinion 47 to the main spur wheel, 4. I

The principle upon which the reverse is based is exactly the same as that upon which the gears work, it being simply a repetition of the gearing mechanism only in such a 1118 11- ner that a gear of less than 0% is ob tained, thereby causing the main spur wheel to rotate in the reverse direction to the shell.

The parts in use are shown in Fig. 11. Thespur wheel 55 which is integral with the clutch 14 is brought' into engagement with the spur wheel56 on the planet spindle 2 by the longitudinal movement of the rod6. Motion istransmitted to the planet spindle 2 as in the former cases the spur wheel 55 be-' ing keyed to the stationary spindle byaproj ection which extends into the shaft slot andonly allows of its longitudinal movement.

In the modification shown in Fig. 12 the spu'r wheel 55 is loose on the stationary spine dle 1 and in the reverse it is locked to the shaft frictionface 19 by rod 6 and clutch 14. This method is an improvement on the other inasmuch as the spur wheel 55 is always in engagement with the spur wheel 56 and is brought in and out of engagement with the stationary spindle 1 instead of in and out of engagement with the spur wheel 56. By

this means the planet spindle is rotated and the motion conveyed to 4 by the pinion 47.

The motion is transmitted from the main ,spur wheel 4 to the car or sprocket wheel the main spur wheel axles 57, 58 as before stated through the me- (hum of the bevel wheel 49. This bevel wheel 49 being loosely mounted may have studs'59 on each of which is mounted a double spur wheel 60 the smallest diameter 61 of which is in engagement with a spur wheel 62 on the axle 58 see Fig. 2 for one car wheel or sprocket chain wheel and the largest diameter 64 engaging a wheel 65 with internal teeth 66 on the axle 57 for the other car or sprocket wheel.

In the modification shown in Fig. 12 provision is made for gearing down instead of up, and the main spur wheel 4 has a sleeve 68 on the stationary spindle 1 driven from the balance'g'ear 49, 65 which also drives asec- 0nd sleeve 69 mounted on first named sleeve 68 which carries the bevel pinion 7 0 driving the bevel wheel 72 on the one car wheel axle 57 and also drives the other sleeve 68 carrying the bevel pinion 63 driving the bevel wheel 71 on the other car wheel axle 58 the balance gear 49, 65 in this'case being mounted upon the planet spindle 2.

The bevel wheel 72 may be fixed on one end of a sleeve "73 loosely mounted on one axle 58 carried in the hollow of the axle 57 for the other side. On the sleeve 58' may be mounted another sleeve 74 which may run on bearings 75 and on this sleeve 74 may be mounted the cams 7, 8, which may be oper-' ated by a lever or toothed rack 76 and this sleeve 74 may also carry an arm 77 in which the stationary spindle is fixed. Extra support may be obtained by the use of the stay 78 which is rovided to form a bearing for the outer end 0 the shell 37.

The compensating mechanism shown in Fig. 12 is the sameas that above described with reference .to Fig; 2;
